In the current literature, little is known about the role of Siberian High (SbH) on precipitation variability over the Kingdom of Saudi Arabia. The technique of centers of action (COA) has been employed here to study the possible impact of SbH on interannual variations in winter precipitation over the kingdom because the COA methodology helps us to find changes in interannual variations of pressure intensity, latitudinal and longitudinal positions of the pressure system using sea-level pressure data. The results show that there are two regions of the kingdom whose precipitation is significantly affected by SbH, the southeast region and the region from northeast to central Saudi Arabia. The precipitation over the southeastern region is significantly influenced by the intensity of SbH as well as its meridional displacement whereas the precipitation variability from northeast to the central kingdom is significantly influenced by the meridional displacement of SbH. The effect of remote forcings of North Atlantic Oscillation and El Niño–Southern Oscillation on precipitation of the kingdom has also been discussed in the paper. The empirical results can be understood by the mechanism of changes and circulations in the atmosphere.

在目前的文献中，关于西伯利亚高压（SbH）对沙特阿拉伯王国降水变化的作用了解甚少。这里使用了作用中心技术（COA）来研究SbH对沙特王国冬季降水的年际变化的可能影响，因为COA方法论可以帮助我们发现压力强度，纬向和纵向位置的年际变化的变化。使用海平面压力数据的压力系统。结果表明，沙特阿拉伯有两个地区的降水受SbH的影响很大，即东南地区和东北到沙特阿拉伯中部地区。SbH的强度及其子午位移严重影响东南地区的降水，而SbH的子午位移严重影响从东北到中部王国的降水变化。本文还讨论了北大西洋涛动和厄尔尼诺-南部涛动的遥远强迫对王国降水的影响。经验结果可以通过大气变化和环流的机理来理解。
